After two decades of owning Mercedes, BMW, and Infiniti, I decided to test the Cadillac STS. I selected the STS over the Mercedes E350 and Infiniti M35. Its ride is firm but smooth. The electronic features are fantastic. Remote start with heated seats and steering wheel make cold mornings easier. The 15 speaker Bose stereo with XM radio is FANTASTIC. I get about 20 MPG on my commute and on a recent road trip I averaged 23 MPG at 80 MPH.
